@rezance Thanks for sharing your findings on this one.
Note that your “GRUB_CMDLINE_LINUX_DEFAULT” is now no longer representative of our modern installer as we have recently dropped the “ipv6.disable=1” option. Also, if one changes the /etc/default/grub file it is required, to enact the change, to run the
grub2-mkconfig -o /boot/grub2/grub.cfg
after each such edit.
See the following post for some details where we similarly discussed how to remove, and instantiate, the ipv6.disable option:
Also note that if one is building ones own installer via our:
Then you can also just add your suggested nomodeset option to the kiwi-ng config before creation the installer. The change would be made, for the x86_64 profile for example, in the following line:
There are equivalent lines for the other installer profiles, Pi4 for example.
That way the resulting installer will instantiate installs that already have this change in place.
How about we add this advice to that repository, i.e. we add a little note to the bottom of the readme, say that indicates ‘special’ options required for known hardware compatibility? Do you fancy opening an issue for this, and potentially a pull request, in the installer repository? Issues:
I.e. entitled “Add ‘Custom kernel options’ section to Readme”
With a description including your example of the HP microserver gen10 requirement. As you say other AMD equipped systems may also benefit from this addition. I’m reluctant to add this by default however as then we move further away from our upstream JeOS appliance image examples.
Let me know if you don’t fancy embarking on the issue/pr and I’ll see to it myself.
Thanks again for sharing your findings on this one. Much appreciated. And I’m glad you got this sorted.
